Abstract:
The Modular Ocean Model (MOM) is a numerical representation of the ocean's hydrostatic primitive equations, and it is designed primarily as a tool for studying the global ocean climate system. MOM4 is the latest version of the GFDL ocean model whose origins date back to the pioneering work of Kirk Bryan and Mike Cox in the 1960s-1980s. It is ... developed and supported by researchers at NOAA's Geophysical Fluid Dynamics Laboratory (GFDL), with contributions also provided by researchers worldwide.

Presently, MOM4 is undergoing its second phase of beta-testing (MOM4-beta2). This is a fully open beta test, so anyone wishing to obtain the code can do so. The purpose of this web page is to provide general information about MOM4, and particular information for how to download and run the code.
